The semi-major axis of Ceres' orbit about the Sun is 2.77 Astronomical Units (A.U.) or roughly 257 million miles (414 million kilometers). At the time of the Hubble observations, Ceres was roughly 1.63 A.U. from Earth.

This image is a composite of many separate exposures made by the ACS HRC instrument on the Hubble Space Telescope using several different filters. Two filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are:
